  • Integrated linear power detection in an RF power amplifier
    Patent number: 8319557
    Abstract: A radio frequency (RF) power amplifier system having a power detection feature includes a balanced power amplifier, an in-phase branch current detector, an out-of-phase branch current detector, and detection circuitry. The balanced power amplifier includes a phase splitter, an in-phase power amplifier branch, an out-of-phase power amplifier branch, and a phase combiner. The in-phase branch current detector provides an indication of current in the in-phase power amplifier branch. The out-of-phase branch current detector provides an indication of current in the out-of-phase power amplifier branch. The detection circuitry combines the indications of current in the in-phase and out-of-phase power amplifier branches to produce an indication of current in the balanced power amplifier.
